GST95300EN06 Radiator Flush Cleans Cooling System (300 ml)

Excellent

Easy to use and great Flush but maybe you need to buy 2 and do the process again after a week

Good product but better to use two bottles for V6 and V8 engines.

Received the item with seal broken, some leak in the plastic bag. Not sure if content is fine, I was at the workshop already and have no options. I threw it away and bought new one from nearby shop. Check seal once you receive item, do not wait till you at the workshop.

جيد

I tried flushing the coolant system on my Honda civic 10th sedan but the cleaning power is very weak. I came second time with Finish washing machine descaling solution which has an anti foamer agent too, and that one worked wonders! I don't recommend this product. Too weak.

Nothing change anything ... Not clean car cooling system i use as a STP instruction , but nothing change

It seems a good product as per specification.

Noise level wasn't high to start with but quieter still now...radiator wasn't dirty but coolant flush a must as new hoses n water pump installed + cam belt ..diagnostics showed all in order...

Very very good quality product as always stp has provided great results either radiator flush or petrol fuel system cleaners highly recommended

herhalde iyi üründür fakat bana gelen şişe hava almış. biraz dökülmüş... özelliğini kaybetmediyse iş yapar.

Good, it done what it was meant to

To me if we use a full shampoo sachet with water and flush it out at the garage it can do the same job
